Success from Our Learners

"Cybrary really helped me get up to speed and acquire a baseline level of technical knowledge. It offers a far more comprehensive approach than just learning from a book. It actually shows you how to apply cybersecurity processes in a hands-on way"

Don Gates

Principal Systems Engineer/SAIC

"Cybrary’s SOC Analyst career path was the difference maker, and was instrumental in me landing my new job. I was able to show the employer that I had the right knowledge and the hands-on skills to execute the role."

Cory

Cybersecurity analyst/

"I was able to earn my CISSP certification within 60 days of signing up for Cybrary Insider Pro and got hired as a Security Analyst conducting security assessments and penetration testing within 120 days. This certainly wouldn’t have been possible without the support of the Cybrary mentor community."

Mike

Security Engineer and Pentester/

"Becoming a Cybrary Insider Pro was a total game changer. Cybrary was instrumental in helping me break into cybersecurity, despite having no prior IT experience or security-related degree. Their career paths gave me clear direction, the instructors had real-world experience, and the virtual labs let me gain hands-on skills I could confidently put on my resume and speak to in interviews."

Cassandra

Information Security Analyst/Cisco Systems

"I was able to earn both my Security+ and CySA+ in two months. I give all the credit to Cybrary. I’m also proud to announce I recently accepted a job as a Cyber Systems Engineer at BDO... I always try to debunk the idea that you can't get a job without experience or a degree."

Casey

Cyber Systems Engineer/BDO

"Cybrary has helped me improve my hands-on skills and pass my toughest certification exams, enabling me to achieve 13 advanced certifications and successfully launch my own business. I love the practice tests for certification exams, especially, and appreciate the wide-ranging training options that let me find the best fit for my goals"
